To all 207mm it 71mg/ con/Pern.:

Be it known that l', CLAYTON YVOLOO'IT, a

citizen of the 'United States, residing at llartford, in the county of llartford and State et Connecticut, have invented certain, new and useful Improvements in '.llats, ot' which the following` is a s'lriecitieation.

My invention relates to improvements in mats; and the ol )jects of my invention are simplicit;T and economy of construction and general etliciency in use.

In the accompalivingl drawings, Figure l is a plan view oi' my mat. hig. 2 is a longitudinal section, pai-thr in elevation, of a portion ot' said mat. Fig. il isatransversesection, partl7 in elevation, ot' a portion of said mat. Fig. e is a side elevatimi olil a portion of one of the cross-hars for said mat. Fig. is a horizontal section, partly in planview, ot a portion of said inat. Figs. 6 and 7 are like views showing a modiiication in construction; and Fig. 8 is a transverse section ot a portion ot' my mat, illustrating two modifications.

a designates the transverse hars. l: the longitudinal hars or wires, and c the hand which i' surrounds the edge ot' the mal, all of which l t prefer to t'orin ot' .nietat lith the exception ol the transverse har at i each end of the mat, the transverse hars o are provided with tenons d, which pass through holes in the hand c and are then riveted or headed to firmly unite them to the hand. The transverse hars at eaeh end may, it desired, he provided with like tenons; hut i prel'er to oinit said tenons for the end liars and then secure said hars tothe hand e hy rivets j" at different points alou the length of said har. Each of the transverse hars'is provided with a series of notches open at the upper edge and enlarging downwardlv, thereby Forming notches with overhanging side walls. The

longitudinal hars or wires o are l'ormed ot' i such shape in cross lsection as to lill the notches in the bars c and also to 'project slightly above the top of the hars in which said notches are formed, as shown. I prefer to form these notches and hars or wires of a triangular-form in cross-section and to arrange them with one ot' their corners projecting upwardly, as shown.

All ot' the bars or wires l) may he made of a length which will just till the longitudinal Il space inelosed hy the hand c; or, it' desired, p' apart ot' said wires may he provided With i tenons g, which project through holes in the Y hand e and have their ends riveted, thereby rigidly holding said band in place and bindt ingl the whole together in a hrm and substani tial manner. r ln Fig. 2 the hars (t a and the end portion l of the hand c are shown in transverse sec- I tion on a line which passes through the iniddie portion of one of the bars or wires l) havt ing the tenen g, said har being shown in elevation. In Fig. 3 the transverse section is on a line through the middle of one of the transverse bars a having' atenon, d, said harloeing shown in elevation.

In Figs. 5, (i, and 7 the horizontal sections through the band and hara at the end of the mat are in the same plane as the bottoni of the hars l), said hars being shown in plan view. i ln Fig. t, instead of providing thel'iarsb with a tenen which extends through the hand c, I notch the two sides of the har to forni a dovetailed head and the har o at the end is provided with notches of a eorresponi'lingshape, hut with vertical sides, so1hatsaiddovetailed tenons may he slipped vertically into the witches of the end hars. `When saidhars are i securiul to the hand c hy means of the rivets f, the parts are trml)` hound together. In Fig. 7 l have represented the notches in the end har, a, oi the same Vt'orm as in the othertransverse hars, but beveled or eountersunk upon t theonter side, so that the ends ot the hars l) may he upset or headed, as shown, hetero the end. hai (t, are secured to the hand e.

WYhile l prefer the triangular form for the longitudinal wires or hars l), said hars maybe i rolled or drawnv in the iorm ot a modified trii i angle in cross-section, or square, or round, as sho\ \'n in Fig. S, the notches in the transverse hars being modilied in accordance with the shape ol' the hars intended to he used. In all the forms shown or suggested the notchesfor the principal transverse hars are open at the top and enlarged downwardly, and the lower part of the longitudinal hars or wires is cor respondingly shaped, while their upper part or su inniit, which projects upwardly ahove the upper edges of the transverse bars, is provided with a sharp or rounded longitudinal ridge, thereby forming a series of effective scrapers.

After the parts are separately constructed in the manner described, the several longitudinal bars or wires '(1 are slipped endwise through the notches in the transverse bars (L. The surroundingband can thcnbe secured in place to bind the parts together.

I claim as my invention The herein-described mat, consisting of a surroundi n g band, a series of transverse bars having notches which are open at the top and enlarged downwardly, and a series of longii tudinal bars or wires With their lower parts shaped in cross-section to the form of said notches, While their upper portions, which projectl therefrom, are contracted into a longitudinal ridge, substantially as described, and for the purpose specified.
